1. Definitions

As used in the present specification, the following words and phrases are generally intended to have the meanings as set forth below, except to the extent that the context in which they are used indicates otherwise.

The term “comprise” and variations thereof, such as, “comprises” and “comprising” are to be construed in an open, inclusive sense, that is, as “including, but not limited to.” Further, the singular forms “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise. Thus, reference to “the compound” includes a plurality of such compounds, and reference to “the assay” includes reference to one or more assays and equivalents thereof known to those skilled in the art.

Reference to “about” a value or parameter herein includes (and describes) embodiments that are directed to that value or parameter per se. In certain embodiments, the term “about” includes the indicated amount ±10%. In other embodiments, the term “about” includes the indicated amount ±5%. In certain other embodiments, the term “about” includes the indicated amount ±1%. Also, to the term “about X” includes description of “X”.

Recitation of numeric ranges of values throughout the disclosure is intended to serve as a shorthand notation of referring individually to each separate value falling within the range inclusive of the values defining the range, and each separate value is incorporated in the specification as it were individually recited herein.

Forms of Compound I and salts/co-crystals are provided herein. In one embodiment, reference to a form of Compound I means that at least 50% to 99% (e.g., at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, or at least 99%) of Compound I or a salt or co-crystal thereof present in a composition is in the designated form. For instance, in one embodiment, reference to Compound I HCl Form I means that at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, or at least 99% of the hydrochloride salt of Compound I present in a composition is in Form I.

The term “solid form” refers to a type of solid-state material that includes amorphous as well as crystalline forms.

The term “crystalline form” refers to a solid phase in which the material has a regular ordered internal structure at the molecular level and gives a distinctive X-ray diffraction pattern with defined peaks. Such materials when heated sufficiently will also exhibit the properties of a liquid, but the change from solid to liquid is characterized by a phase change, typically first order (melting point). The term “crystalline form” encompasses co-crystals as defined herein. A distinctive crystalline form may be designated by the term “Form,” Material,” or “Type,” which terms are used interchangeably.

The term “substantially crystalline” as used herein is intended to mean that greater than 50%; or greater than 55%; or greater than 60%; or greater than 65%; or greater than 70%; or greater than 75%; or greater than 80%; or greater than 85%; or greater than 90%; or greater than 95%, or greater than 99% of the compound present in a composition is in crystalline form. “Substantially crystalline” can also refer to material which has no more than about 20%, or no more than about 10%, or no more than about 5%, or no more than about 2% in the amorphous form. Likewise, the term “substantially” when qualifying any form of a compound described herein is intended to mean that greater than 50%; or greater than 55%; or greater than 60%; or greater than 65%; or greater than 70%; or greater than 75%; or greater than 80%; or greater than 85%; or greater than 90%; or greater than 95%, or greater than 99% of the compound is present in the designated form.

The term “amorphous form” refers to a state in which the material lacks long range order at the molecular level and, depending upon temperature, may exhibit the physical properties of a solid or a liquid. Typically such materials do not give distinctive X-ray diffraction patterns.

The term “co-crystal” refers to a molecular complex of a compound and one or more co-crystal formers connected through non-covalent interactions. In some embodiments, the co-crystals disclosed herein may include a non-ionized form of Compound I (e.g., Compound I free base) and one or more non-ionized co-crystal formers, where non-ionized Compound I and the co-crystal former(s) are connected through non-covalent interactions. In some embodiments, co-crystals disclosed herein may include an ionized form of Compound I (e.g., a salt of Compound I) and one or more non-ionized co-crystal formers, where ionized Compound I and the co-crystal former(s) are connected through non-covalent interactions. Co-crystals may additionally be present in anhydrous, solvated or hydrated forms. In some embodiments, there is no hydrogen transfer between the compound and the co-crystal former.

The term “co-crystal former” or “co-former” refers to one or more pharmaceutically acceptable compounds that can be in association with a compound, such as Compound I, to form a co-crystal.

The term “solvate” refers to a complex formed by combining Compound I, or a salt or co-crystal thereof, and a solvent. As used herein, the term “solvate” includes a hydrate (i.e., a solvate when the solvent is water).

The term “desolvated” refers to a Compound I form that is a solvate as described herein, and from which solvent molecules have been partially or completely removed. Desolvation techniques to produce desolvated forms include, without limitation, exposure of a Compound I form (solvate) to a vacuum, subjecting the solvate to elevated temperature, exposing the solvate to a stream of gas, such as air or nitrogen, or any combination thereof. Thus, a desolvated Compound I form can be anhydrous, i.e., completely without solvent molecules, or partially desolvated wherein solvent molecules are present in stoichiometric or non-stoichiometric amounts.

The term “pharmaceutical composition” refers to a pharmaceutical preparation suitable for administration to an intended subject for therapeutic purposes that comprises one or more of the solid forms of Compound I or a salt/co-crystal thereof as described herein. The composition may include at least one pharmaceutically acceptable component to provide an improved formulation of the compound, such as a suitable carrier or excipient.

Any formula or structure given herein, including Compound I, is also intended to represent unlabeled forms as well as isotopically labeled forms of the compounds. Isotopically labeled compounds have structures depicted by the formulae given herein except that one or more atoms are replaced by an atom having a selected atomic mass or mass number. Examples of isotopes that can be incorporated into compounds of the disclosure include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine and chlorine, such as, but not limited to ²H (deuterium, D), ³H (tritium), ¹¹C, ¹³C, ¹⁴C, ¹⁵N, ¹⁸F, ³¹P, ³²P, ³⁵S, ³⁶Cl and ¹²⁵I. Various isotopically labeled compounds of the present disclosure, for example those into which isotopes such as ³H, ¹³C and ¹⁴C are incorporated, may be prepared. Such isotopically labeled compounds may be useful in metabolic studies, reaction kinetic studies, detection or imaging techniques, such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT) including drug or substrate tissue distribution assays or in radioactive treatment of patients.

The disclosure also includes “deuterated analogs” of compounds of Formula I in which from 1 to n hydrogens attached to a carbon atom is/are replaced by deuterium, in which n is the number of hydrogens in the molecule. Such compounds exhibit increased resistance to metabolism and are thus useful for increasing the half-life of any compound of Formula I when administered to a mammal, particularly a human See, for example, Foster, “Deuterium Isotope Effects in Studies of Drug Metabolism,” Trends Pharmacol. Sci. 5(12):524-527 (1984). Such compounds are synthesized by means well known in the art, for example by employing starting materials in which one or more hydrogens have been replaced by deuterium.

Deuterium labelled or substituted therapeutic compounds of the disclosure may have improved DMPK (drug metabolism and pharmacokinetics) properties, relating to distribution, metabolism and excretion (ADME). Substitution with heavier isotopes such as deuterium may afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life, reduced dosage requirements and/or an improvement in therapeutic index. An ¹⁸F labeled compound may be useful for PET or SPECT studies. Isotopically labeled compounds of this disclosure and prodrugs thereof can generally be prepared by carrying out the procedures disclosed in the schemes or in the examples and preparations described below by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent. It is understood that deuterium in this context is regarded as a substituent in the compound of Formula I.

The concentration of such a heavier isotope, specifically deuterium, may be defined by an isotopic enrichment factor. In the compounds of this disclosure any atom not specifically designated as a particular isotope is meant to represent any stable isotope of that atom. Unless otherwise stated, when a position is designated specifically as “H” or “hydrogen” the position is understood to have hydrogen at its natural abundance isotopic composition. Accordingly, in the compounds of this disclosure any atom specifically designated as a deuterium (D) is meant to represent deuterium.

The term “treatment” or “treating” refers to an approach for obtaining beneficial or desired results including clinical results. Beneficial or desired clinical results may include one or more of the following: a) inhibiting the disease or condition (e.g., decreasing one or more symptoms resulting from the disease or condition, and/or diminishing the extent of the disease or condition); b) slowing or arresting the development of one or more clinical symptoms associated with the disease or condition (e.g., stabilizing the disease or condition, preventing or delaying the worsening or progression of the disease or condition, and/or preventing or delaying the spread (e.g., metastasis) of the disease or condition); and/or c) relieving the disease, that is, causing the regression of clinical symptoms (e.g., ameliorating the disease state, providing partial or total remission of the disease or condition, enhancing effect of another medication, delaying the progression of the disease, increasing the quality of life, and/or prolonging survival.

The term “prevention” or “preventing” refers to any treatment of a disease or condition that causes the clinical symptoms of the disease or condition not to develop. Compounds as described herein may, in some embodiments, be administered to a subject (including a human) who is at risk or has a family history of the disease or condition.

The term “administering” refers to oral administration, administration as a suppository, topical contact, intravenous, intraperitoneal, intramuscular, intralesional, intranasal or subcutaneous administration, or the implantation of a slow-release device e.g., a mini-osmotic pump, to a subject. Administration is by any route, including parenteral and transmucosal (e.g., buccal, sublingual, palatal, gingival, nasal, vaginal, rectal, or transdermal). Parenteral administration includes, e.g., intravenous, intramuscular, intra-arteriole, intradermal, subcutaneous, intraperitoneal, intraventricular, and intracranial. Other modes of delivery include, but are not limited to, the use of liposomal formulations, intravenous infusion, transdermal patches, etc.

The term “modulating” or “modulate” refers to an effect of altering a biological activity, especially a biological activity associated with a particular biomolecule such as a protein kinase. For example, an agonist or antagonist of a particular biomolecule modulates the activity of that biomolecule, e.g., an enzyme, by either increasing (e.g., agonist, activator), or decreasing (e.g., antagonist, inhibitor) the activity of the biomolecule, such as an enzyme. Such activity is typically indicated in terms of an inhibitory concentration (IC₅₀) or excitation concentration (EC₅₀) of the compound for an inhibitor or activator, respectively, with respect to, for example, an enzyme.

The term “protein kinase mediated disease or condition,” refers to a disease or condition in which the biological function of a protein kinase, including any mutations thereof, affects the development, course, and/or symptoms of the disease or condition, and/or in which modulation of the protein kinase alters the development, course, and/or symptoms of the disease or condition. The protein kinase mediated disease or condition includes a disease or condition for which inhibition provides a therapeutic benefit, e.g. wherein treatment with protein kinase inhibitor(s), including one or more solid, crystalline or polymorphs of Compound I or as described herein, provides a therapeutic benefit to the subject suffering from or at risk of the disease or condition.

The term “subject” refers to a living organism that is treated with compounds as described herein, including, but not limited to, any mammal, such as a human, other primates, sports animals, animals of commercial interest such as cattle, farm animals such as horses, or pets such as dogs and cats.

The term “pharmaceutically acceptable” indicates that the indicated material does not have properties that would cause a reasonably prudent medical practitioner to avoid administration of the material to a patient, taking into consideration the disease or conditions to be treated and the respective route of administration. For example, it is commonly required that such a material be essentially sterile, e.g., for injectibles.

The term “therapeutically effective amount” or “effective amount” of a compound described herein means an amount sufficient to effect treatment when administered to a subject, to provide a therapeutic benefit such as amelioration of symptoms or slowing of disease progression. The therapeutically effective amount may vary depending on the subject, and disease or condition being treated, the weight and age of the subject, the severity of the disease or condition, and the manner of administering, which can readily be determined by one or ordinary skill in the art.

The phrase “substantially as shown in” a figure as applied to X-ray powder diffractogram is meant to include a variation of ±0.2° 2θ for each peak, as applied to DSC thermograms is meant to include a variation of ±3° Celsius, as applied to DSC thermograms is meant to include a variation of ±3° Celsius, and as applied to thermogravimetric analysis (TGA) is meant to include a variation of ±2% in weight loss or gain.

In the context of the use, testing, or screening of compounds that are or may be modulators, the term “contacting” means that the compound(s) are caused to be in sufficient proximity to a particular molecule, complex, cell, tissue, organism, or other specified material that potential binding interactions and/or chemical reaction between the compound and other specified material can occur.

2. Forms of Cerdulatinib

As described generally above, the present disclosure provides crystalline forms of Compound I and salts/co-crystals thereof. Additional forms (including amorphous forms) are also discussed further herein. Crystalline forms of Compound I (free base), the crystalline forms of salts/co-crystals of Compound I, and other forms (e.g., amorphous or disordered forms) of Compound I (free base) and salts/co-crystals thereof, are collectively referred to herein as “forms of Compound I.”

The hydrochloride salts/co-crystals of Compound I were unexpectedly and surprisingly found to exhibit superior stability, hygroscopicity, solubility, and thermal properties compared to Compound I, and other solid forms of Compound I, and particularly the esylate, edisylate, mesylate, naphthalene disulfonate, sulfate, and tosylate salts/co-crystals of Compound I. For example, the mesylate and esylate salts/co-crystals of Compound I, while highly soluble, exhibited multiple form variations/solvations during handling without the isolation of a single, stable crystalline entity. The sulfate salts/co-crystals of Compound I were found to be highly insoluble and exhibited the form variation noted for the mesylate and esylate salts/co-crystals of Compound I. Other salts/co-crystals (e.g., the edisylate, naphthalene disulfonate, and tosylate salts/co-crystals) of Compound I also exhibited form variation.

Further, the mono-hydrochloride (e.g., Compound I HCl Form I) and mono-mesylate salts/co-crystals of Compound I were found to be more stable than the corresponding bis-salts/co-crystals thereof, as the bis-salts/co-crystals dissociated back to the mono version when handled in solution. Moreover, the solid forms of the mono-hydrochloride salt/co-crystal of Compound I (e.g., Compound I HCl Form I) was found to exhibit superior stability compared to solid forms of the mono-mesylate salts/co-crystals of Compound I.

Compound I HCl Form I was surprisingly and unexpectedly found to be the most physico-chemically stable solid form of Compound I. As discussed in greater detail below, Compound I HCl Form I is stable at room temperature under ambient conditions and remains crystalline while hydrated. The hydration behavior of Compound I HCl Form I is reversible, such that rehydration of Compound I HCl Form I returns the single, crystalline form, allowing Compound I HCl Form I be stored at ambient conditions without desiccant.

It is also contemplated that the mono-hydrochloride (Compound I HCl Form I) salt exhibits improved, compared to other salts, gross from variation, DVS stability, solubility and crystallization process control. It is further contemplated that the sulfonate salts (e.g., crystalline forms of the esylate, mesylate, isethionate, naphthalenesulfonate, chlorobenzenesulfate, tosylate, besylate, edisylate, and/or camphorsulfonate), compared to other salts, exhibits improved solubility.

The software used for data collection was X'Pert Data Collector, version 2.2f and the data was presented using X'Pert Data Viewer, version 1.2d.

Samples were run under ambient conditions and were analyzed by transmission foil XRPD, using the powder as received. Approximately 2-5 mg of the sample was mounted on a 96 position sample plate supported on a polyimide (Kapton, 12.7 μm thickness) film. Data was collected in the range 3-40° 2 with a continuous scan (speed of 0.146° 2/s).

b. Differential Scanning calorimetry (DSC)

DSC data was collected on a PerkinElmer Pyris 6 DSC. The instrument was verified for energy and temperature calibration using certified indium. A predefined amount in milligrams mg of the sample was placed in a pin holed aluminum pan and heated at 20° C.·min⁻¹ from 30° C. to 350° C. The instrument control and data analysis was Pyris Software v9.0.1.0174.

c. Thermo-Gravimetric Analysis (TGA)

TGA data were collected on a Pyris 1 TGA equipped with a 20 position autosampler. The instrument was calibrated using certified alumel and perkalloy. A predefined amount in milligrams of the sample was loaded onto a pre-weighed aluminum crucible and was heated at 40° C.·min⁻¹ from ambient temperature to 500° C. A nitrogen purge at 20 mL·min⁻¹ was maintained over the sample. The instrument control and data analysis was Pyris Software v9.0.1.0174.

d. Gravimetric Vapor Sorption (GVS)

Sorption isotherms were obtained using a Hiden Isochema moisture sorption analyser (model IGAsorp), controlled by IGAsorp Systems Software v6.50.48. The sample was maintained at a constant temperature (25° C.) by the instrument controls. The humidity was controlled by mixing streams of dry and wet nitrogen, with a total flow of 250 mL·min⁻¹. The instrument was verified for relative humidity content by measuring three calibrated Rotronic salt solutions (10-50-88%). The weight change of the sample was monitored as a function of humidity by a microbalance (accuracy+/−0.005 mg). A defined amount of sample was placed in a tared mesh stainless steel basket under ambient conditions. A full experimental cycle consisted of two scans (sorption and desorption) at a constant temperature (25° C.) and 10% RH intervals over a 10-90% range (90 minutes for each humidity level). This type of experiment should demonstrate the ability of samples studied to absorb moisture (or not) over a set of well determined humidity ranges.

e. Nuclear Magnetic Resonance (NMR) ¹H

NMR spectra were collected on a Bruker 270 MHz instrument equipped with an auto-sampler and controlled by a DRX400 console. Automated experiments were acquired using Delta NMR Processing & Control Software version 4.3. Samples were prepared in d6-DMSO, unless otherwise stated. Analysis was carried out using (ACD/Specmanager 7.11).

f. Hot Stage Microscopy (HSM)

Hot Stage Microscopy was carried out using a Leica DME polarized light microscope combined with a Mettler-Toledo MTFP82HT hot-stage and a digital video camera for image capture. A small amount of each sample was placed onto a glass slide with individual particles separated as well as possible. The sample was viewed with appropriate magnification and partially polarized light, whilst being heated from ambient temperature typically at 20° C.·min-1.

g. Thermodynamic Aqueous Solubility by HPLC

Aqueous solubility was determined by suspending sufficient compound in HPLC grade water to give a maximum final concentration of ≥10 mg mL⁻¹ of the parent free-form of the compound. The suspension was equilibrated at 25° C. for 24 hours. The suspension was then passed through a filter into an HPLC vial. The filtrate was then diluted by an appropriate factor. Quantification was executed by HPLC with reference to a standard solution of approximately 1 mg·mL⁻¹ in acetonitrile:water (1:1). Different volumes of the standard, diluted and undiluted sample solutions were injected. The solubility was calculated using the peak areas determined by integration of the peak found at the same retention time as the principal peak in the standard injection. HPLC method parameters are described in Table 1 and Table 2.

Analysis was performed on an Agilent 1100 series liquid chromatography, equipped with a UV detector (DAD or VWD) @ 254 nm and using Chemstation Rev.B.01.03 software for data processing.

2. Solid Forms of Compound I (Free Base)

a. Compound I and Compound I Hydrochloride Salt

Compound I and Compound I hydrochloride salt can be prepared according to Scheme 1. An exemplifying synthesis is described below.

Step 1: Conversion of Compound D-1 to Compound C

86.0 Kg of DMF, 76.5 kg of formamide, and 45.5 kg of Compound D-1, were charged in a reactor. To this mixture after having reached an internal temperature of 0-10° C., 84.0 kg of sodium ethoxide 21% were added keeping the internal temperature between 0-10° C. The mixture was warmed up to 50° C. and stirred for 60 minutes. In-process control showed that residual content of Compound D-1 was 3.14%. The mixture was cooled till 0° C. and 900 L of water were added, after having finished the water addition, the reaction was cooled down again till −5° C. and it was left stirring for 16 hours. The mixture was filtered and the filter cake was washed with 50 kg of cold methyl tert-butylether.

The filter cake (52.95 kg) containing Compound C was forwarded to a dryer. Drying of Compound C crude wet product (60° C. for 21 hours and 40 minutes) gave 37.30 kg (92.6% yield) of Compound C crude dry product. Purity 97.54%.

Step 2: Synthesis of Compound I

235 Kg of NMP, and 32.1 kg of Compound C crude dry product were charged to a reactor. The internal temperature was set at between 0-10° C. 72.95 Kg of MCPBA were charged while keeping the temperature under 5° C. The mixture was then warmed up till 25° C. and stirred for 1 hour. IPC showed that residual content of Compound C was 0.00% for oxidative reaction. The mixture was kept stirring at 25° C. for a further hour.

To the above mixture, 40.05 kg of Compound B was added. The internal temperature was set at 40° C. and the mixture was stirred overnight for 17 hours and 17 minutes, and then for additional 4 hours. In-process control showed that residual content of Compound A-2+Compound A-3 was 2.05%. The mixture was cooled down to 3° C., and a pre-cooled basic solution of water (642 L) and NaHCO₃ (48 kg) was added to the mixture. The mixture was stirred for 1 hour and then water (193 L) was added keeping the internal temperature between 0-10° C. The mixture was stirred for 40 minutes. Solid was isolated by filtration (filter-dryer equipped with 20 μm mesh) keeping squeezing the cake with both N₂/vacuum for 51 hours.

Compound I crude wet product (106.9 kg) was then re-charged in the reactor and slurried at 25° C. for 9 hours with water (1434 L).

Solid was isolated by filtration (filter-dryer equipped with 20 μm mesh cloth) keeping squeezing the cake with both N₂/vacuum for 60 hours.

Wet solid was respectively slurried and squeezing four times more in the filter-dryer using water (877 L).

Solid was then forwarded to the filter-dryer for isolation and drying (43° C. under vacuum for 20 hours). Compound I crude dry product overall yield was 88% (63.76 kg) with purity of 90.84%.

Step 3: Synthesis of Compound I Hydrochloride Salt

252 Kg of DMSO and 56.2 kg of Compound I were charged in the reactor. The mixture was warmed up to 75° C. and stirred till complete dissolution. 664 Kg of EtOH abs. was added and the reaction was stirred for 30 minutes. Keeping the internal temperature in between 70-80° C. (72.9° C.), an acidic solution made by mixing 347 kg of water and 43 kg of HCl 33% w/w was added. The reaction was stirred for further 30 minutes. The mixture was then cooled down to 20° C. and stirred for 19 hours. Solid was then forwarded to the filter-dryer (20 μm mesh cloth) for isolation. Wet solid was respectively slurried and squeezing twice directly in the filter-dryer using EtOH (1073 L), and then dried (at 35° C. under vacuum for 50 hours). Compound I hydrochloride salt yield was 58.4% (35.44 kg) with a purity of 99.41%.

b. Compound I Form I

Compound I Form I is crystalline as determined via XRPD analysis (FIG. 1). Compound I Form I can be characterized by an X-ray powder diffractogram comprising the following peaks: 16.6, 18.0, and 23.7° 2θ±0.2° 2θ.

In one embodiment, Compound I Form I is formed from a hydrochloride salt of Compound I, where said hydrochloride salt is prepared according to:

A suspension of Compound I (10.0 g) in IPA (50 mL) and 2 M aq. HCl (50 mL) was heated to 45-50° C. and stirred at this temperature for 18 hours before cooling to 25° C. The solid was collected via vacuum filtration and washed with 1:1 IPA:2M aq. HCl (100 mL), IPA (100 mL) and methyl tert-butylether (100 mL). The dried solid gave a Compound I hydrochloride salt in a yield of 7.9 g (73.15%).

The Compound I hydrochloride (about 3.5 g, about 7 mmol) was suspended in EtOAc (about 35 mL) and stirred during the addition of saturated K₂CO₃ (about 35 mL). The suspension was mixed and heated at about 50° C. for about 4 hours, then cooled, filtered, and washed with EtOAc and water. The resulting solid was dried in vacuo at about 45° C. to produce Compound I Form I.

In one embodiment, Compound I Form I is also formed from the hydrochloride salt starting material using THF and 1N NaOH.

b. Compound I Form II

Compound I Form II is crystalline as determined via XRPD analysis (FIG. 2). Compound I Form II can be characterized by an X-ray powder diffractogram comprising the following peaks: 13.2, 18.7, and 22.0° 2θ±0.2° 2θ.

In one embodiment, Compound I Form II is formed from the aforementioned hydrochloride starting material using EtOAc/THF (9:1) and 1N NaOH at 50° C. Compound I Form II was isolated from a slurry in THF and EtOAc.

3. Salt/Co-Crystal Screen of Compound I

A salt/co-crystal screen was performed using Compound I Form I as the starting material.

The solubility of Compound I Form I in various solvents was first determined and summarized in Table 3.

TABLE 3 Solubility of Compound I Form I Mass/vol Solvent Observations 25 mg/1 mL DCM about 10 mg 25 mg/1 mL EtOAc <5 mg 25 mg/1 mL Heptane <5 mg 25 mg/1 mL IPA <5 mg 25 mg/1 mL THF <5 mg 25 mg/1 mL Acetone <5 mg 25 mg/1 mL MeOH <5 mg 25 mg/1 mL TBME <5 mg 25 mg/1 mL Toluene about 10 mg 25 mg/1 mL Acetonitrile <5 mg

The combination of Compound I Form I in THF, toluene, or acetonitrile formed slurries. A solution of Compound I Form I in DMSO was selected for the salt/co-crystal screen.

Co-formers used in the salt/co-crystal screen included hydrochloric acid, naphthalene-1,5-disulfonic acid, sulfuric acid, ethane-1,2-disulfonic acid, ethane sulfonic acid, p-tolyl sulfonic acid, and methane sulfonic acid.

Salts/co-crystals of Compound I were obtained by combining about 20 mg of Compound I Form I in DMSO (about 5 M) and about 1 equivalent of a selected co-former (1M stock THF) in various solvents such as NMP, DMSO, DMF, 3-Me-1-BuOH, n-BuOAc, toluene, water, IPA, CH₃CN, MEK, EtOH and THF. Samples that resulted in solid material were dried at 40° C. in vacuo and analyzed by XRPD. Exemplary salts/co-crystals of Compound I and their respective solid forms are summarized in Table 4 below.

4. Scale Up Formation of Salts/Co-Crystals of Compound I

An initial scale up formation (“first scale up”) of various crystalline salts/co-crystals of Compound I was performed. The solvents selected for the first scale up were those that yielded a good diffraction pattern in the salt screening experiments described in Table 4 above. The results for the first scale up are summarized below in Table 5.

TABLE 5 First Scale Up Formation of Salts/Co-Crystals of Compound I Solvent XRPD HSM TGA GVS Comp. I Toluene Form I Melt around Gradual Not Esylate IPA Form I 250° C. weight loss of hygroscopic about 7% up to between 0 to about 250° C. about 60% with major RH; about 5 onset at about mg of weight 316° C. uptake between about 60% to about 90% Comp.

Comparison of the XRPD results provided in tables 4 and 5 reveals form variation between the initial salt screening experiments and the initial scale up formation for the edisylate, naphthalene disulfonate, and tosylate salts/co-crystals of Compound I. The esylate, mesylate sulfate and hydrochloride salts/co-crystals of Compound I did not appear to exhibit such form variation, and were thus selected for subsequent scale-up experiments (“second scale up”) as described in sub-sections (a)-(d) and Table 6 below.

a. Compound I Esylate

About 200 mg of Compound I (free base) in DMSO (about 0.5M, about 0.9 mL) was charged to a hot (about 70° C.) tube comprising toluene or IPA (about 15 vols.). About 1 equivalent of an ethane sulfonic acid was added as a 1M solution in THF to the Compound I (free base) solution. The resulting solution/suspension was held isothermal for about 4 hours and cooled overnight prior to filtration, drying, and analysis.

X-ray powder diffractograms for Compound I esylate prepared from toluene and IPA in the second scale up process are shown in FIG. 30A and FIG. 30B, respectively. X-ray powder diffractograms for Compound I esylate Form I prepared from IPA and toluene during the first scale up process are provided in FIG. 30C and FIG. 30D, respectively.

Comparison of FIG. 30A and FIG. 30D indicates that the first and second scale up formation of Compound I esylate via toluene resulted in different crystalline forms. The second scale up formation of Compound I esylate via toluene resulted in a crystalline material (Compound I esylate Material A), which is likely a mixture of crystalline forms.

Comparison of FIG. 30B and FIG. 30C indicates that the first and second scale up formation of Compound I esylate via IPA also resulted in different crystalline forms. The second scale up formation of Compound I esylate via IPA resulted in a crystalline material (Compound I esylate Material B), which is likely a mixture of crystalline forms.

FIG. 31 shows an overlay of the differential scanning calorimetry (DSC) curves and thermogravimetric analysis (TGA) thermograms for Compound I esylate Material A and Material B. The DSC/TGA data for both samples produce a significant endotherm at about 250° C., followed by decomposition, indicating that both samples likely include at least one same form. Compound I Material A shows the presence of at least one other crystalline form by DSC, for example, at about 155° C. by DSC that corresponds to a mass loss by TGA from greater than about 100° C. The mass loss may correspond to about one mole of water, suggesting a hydrated sample. The mass loss of about 1.57% for Compound I Material B may equate to a hemi-hydrate. Both these materials (Compound I Material A and Material B) are hygroscopic.

b. Compound I Sulfate

About 200 mg of Compound I (free base) in DMSO (about 0.5M, about 0.9 mL) was charged to a hot (about 70° C.) tube comprising water or IPA (about 15 vols.). About 1 equivalent of a sulfuric acid was added as a 1M solution in THF to the Compound I (free base) solution. The resulting solution/suspension was held isothermal for about 4 hours and cooled overnight prior to filtration, drying, and analysis.

X-ray powder diffractograms for Compound I sulfate prepared from water and IPA in the second scale up process are shown in FIG. 32A and FIG. 32B, respectively. X-ray powder diffractograms for Compound I sulfate Form II prepared from water and Compound I sulfate Form I prepared from IPA during the first scale up process are provided in FIG. 32C and FIG. 32D, respectively.

Comparison of FIG. 32A and FIG. 32C indicates that the first and second scale up formation of Compound I sulfate via water resulted in substantially the same crystalline form (Compound I sulfate Form II).

Comparison of FIG. 32B and FIG. 32D indicates that the first and second scale up formation of Compound I sulfate via IPA resulted in substantially similar crystalline forms. For instance, the second scale up formation of Compound I sulfate via IPA resulted in crystalline form substantially similar to Compound I sulfate Form I, with the likely presence of at least one additional form.

FIG. 33 shows an overlay of the DSC curve and TGA thermogram for the crystalline form of Compound I sulfate prepared from water during the second scale up process. FIG. 34 shows an overlay of the DSC curve and TGA thermogram for the crystalline form of Compound I sulfate prepared from IPA during the second scale up process. The thermal analysis indicates that the Compound I sulfate sample prepared from water dries in the TGA (surface water likely under N₂ stream below about 100° C.), followed by loss of water above about 100° C., which may equate to a hemi-hydrate monosulfate or mono-hydrate hemisulfate. The gravimetric vapor sorption (GVS) isotherm (not shown) also indicates a facile pick-up of surface moisture for this sample. A similar result is obtained for the Compound I sulfate sample prepared from IPA, with about one mole mass of water being lost after about 100° C., and no significant endotherms present in the DSC before the melting decomposition at about 269° C.

c. Compound I HCl

About 200 mg of Compound I (free base) in DMSO (about 0.5M, about 0.9 mL) was charged to a hot (about 70° C.) tube comprising ethanol or acetonitrile (about 15 vols.). About 2 equivalents of hydrochloric acid (aq.) was added as a 1M solution in THF to the Compound I (free base) solution comprising ethanol. About 1 equivalent of hydrochloric acid (dry) was added as a 1M solution in THF to the Compound I (free base) solution comprising acetonitrile. The resulting solutions/suspensions were held isothermal for about 4 hours and cooled overnight prior to filtration, drying, and analysis.

The X-ray powder diffractogram for Compound I HCl prepared from aqueous HCl (about 2 equiv.) and ethanol in the second scale up process is shown in FIG. 35A. The X-ray powder diffractogram for Compound I HCl prepared from dry HCl (about 1 equiv.) and acetonitrile in the second scale up process is shown in FIG. 35B. X-ray powder diffractograms for Compound I HCl Form I formed from dry HCl (about 1 equivalent) and water, and from dry HCl (about 1 equivalent) and acetonitrile during the first scale up process are provided in FIG. 35C and FIG. 35D, respectively.

Comparison of FIG. 35A, FIG. 35C, and FIG. 35D indicates that the second scale up formation of Compound I HCl using about 2 equivalents of HCl (aq.) and ethanol resulted in substantially the same crystalline form (Compound I HCl Form I) as the first scale up formation of Compound I HCl using about 2 equivalents of HCl (aq.) and ethanol or about 1 equivalent of HCl (dry) and acetonitrile.

However, as shown in FIG. 35B, the second scale up formation of Compound I HCl using about 1 equivalent of HCl (dry) and acetonitrile resulted in a new form (herein referred to as Form II) not observed in the previous slurry or solution based experiments described in the Examples.

FIG. 36 shows an overlay of the DSC curve and TGA thermogram for the Compound I HCl Form I prepared using HCl (aq.) and ethanol during the second scale up process. The TGA thermogram of said sample ethanol shows a mass loss of approximately 3%; accordingly, said sample may be a hydrate. The DSC curve of said sample comprises an endotherm with an onset at about 288° C. and a peak at about 292° C.

FIG. 37 shows an overlay of the DSC curve and TGA thermogram for Compound I HCl form II formed using about 1 equivalent of HCl (dry) and acetonitrile during the second scale up process. The TGA thermogram of said sample shows a small mass loss below about 50° C., a more significant weight loss of about 4.3% at about 150° C. The DSC curve of said sample comprises an endotherm with an onset at about 225° C. and a peak at about 246° C., and an additional endotherm at with onset at about 277° C. and a peak at 284° C.

Other methods for preparing Compound I HCl Form I include: To ethanol (825 mL) heated at reflux under nitrogen, a polish filtered solution of Compound I free base (55 g) in DMSO (248 mL) was added as a steady stream whilst maintaining the temperature above 74° C. The resulting solution was stirred at reflux for 5 minutes. 1M aqueous HCl (370.4 mL) was then added to the solution as a steady stream maintaining the temperature above 70° C. The resulting green suspension was stirred at 75° C. for 30 minutes before cooling to room temperature overnight. The solid was filtered, washed with ethanol (3×220 mL), water (2×220 mL) and pulled dry for 72 hours. KF analysis at this point indicated 23.7% water. The solid was therefore dried in a vacuum oven at 30° C. for 24 hours. KF analysis indicated 2.4% water. Re-hydration (carried out at 20° C.) increased the water content to 5.37%. Further drying for 30 minutes at 20° C. gave an average KF of 4.3%. The yield of Compound I HCl Form I produced was 55.7 g, 94%. ¹H NMR and HPLC analysis confirmed the identity and purity (98.78%).

d. Compound I Mesylate

About 200 mg of Compound I (free base) in DMSO (about 0.5M, about 0.9 mL) was charged to a hot (about 70° C.) tube comprising ethanol or EtOAc (about 15 vols.). About 1 equivalent of a methane sulfonic acid was added as a 1M solution in THF to the Compound I (free base) solution. The resulting solution/suspension was held isothermal for about 4 hours and cooled overnight prior to filtration, drying, and analysis.

X-ray powder diffractograms for Compound I mesylate prepared from ethanol and EtOAc in the second scale up process are shown in FIG. 38A and FIG. 38B, respectively. X-ray powder diffractograms for Compound I mesylate Form II prepared from water, and Compound I mesylate Form III prepared from ethanol during the first scale up process are provided in FIG. 38C and FIG. 38D, respectively.

Comparison of FIG. 38A and FIG. 38D indicates that the first and second scale up formation of Compound I mesylate via ethanol resulted in different crystalline forms. In particular, the second scale up formation of Compound I mesylate via ethanol resulted in a new crystalline material (Compound I mesylate Material A), which is likely a mixture of crystalline forms.

Comparison of FIG. 38B and FIG. 38D indicates that the second scale up formation of Compound I mesylate via EtOAc and the first scale up formation of Compound I mesylate via ethanol resulted in substantially the same form (Form III), with a few minor differences.

FIG. 39 shows an overlay of the DSC curve and TGA thermogram for Compound I mesylate Material A prepared from ethanol during the second scale up process. The TGA thermogram for Compound I Material A indicates that said material comprises a mixture of forms, with a significant number of small mass losses. The DSC curve for Compound I Material A comprises an endotherm with onset at about 261° C., followed by decomposition.

FIG. 40 shows an overlay of the DSC curve and TGA thermogram for Compound I mesylate Form III prepared from EtOAc during the second scale up process. The thermal analysis for said sample shows a broad endotherm with an onset at about 156° C. corresponding with a mass loss of about 3.1% (indicative of a monohydrate), followed by a subsequent loss of about 2.3%, decomposition, and an endotherm with an onset at about 266° C.

5. Solubility of Salts/Co-Crystals of Compound I

The solubility of the salts/co-crystals of Compound I prepared from the second scale up process was analyzed. The materials recovered after the solubility analysis were evaluated by XRPD to observe any form changes. The results are shown in subsections (a)-(d) below.

a. Compound I HCl

Compound I HCl Form I prepared from about 2 equivalents of aqueous HCl and ethanol was not affected by the solubility analysis (i.e., there was no form change), as shown in the X-ray powder diffractograms of FIG. 41A and FIG. 41B for said sample post and pre solubility analysis, respectively. However, solubility analysis of Compound I HCl Form II formed under anhydrous conditions resulted in phase changes and form change to Compound I HCl Form I, as shown in the X-ray powder diffractograms of FIG. 41C and FIG. 41D for said sample post and pre solubility analysis, respectively.

For the second scale up and solubility experiments, Compound I HCl Form I returned the best results in terms of form reproducibility/stability and actual solubility.

b. Compound I Mesylate

The Compound I mesylate input materials for the solubility analysis were of different crystalline forms (i.e., Compound I mesylate Material A prepared from ethanol (FIG. 42B), and the form of Compound I mesylate prepared from EtOAc (i.e., a form substantially similar to Form III, FIG. 42D). The recovered materials (post solubility analysis) from Compound I mesylate Material A (FIG. 42A) and Compound I mesylate Form III (FIG. 42C) are each characterized by the same form, which is different than the forms of either input material.

c. Compound I Sulfate

The form of Compound I sulfate prepared from water (i.e., a form similar to Compound I sulfate Form II) was not affected by the solubility analysis (i.e., there was no form change), as shown in the X-ray powder diffractograms of FIG. 43A and FIG. 43B for said sample post and pre solubility analysis, respectively. However, solubility analysis of the crystalline form of Compound I sulfate prepared from IPA (i.e., a form substantially similar to Compound I sulfate Form I) resulted in a form change to Compound I sulfate Form II, as shown in the X-ray powder diffractograms of FIG. 43C and FIG. 43D for said sample pre and post solubility analysis, respectively.

d. Compound I Esylate

The Compound I esylate input materials for the solubility analysis were of different crystalline forms (i.e., Compound I esylate Material A prepared from toluene, and Compound I esylate Material B prepared from IPA). The recovered materials (post solubility analysis) from Compound I mesylate Material A (FIG. 44A) and Compound I esylate Material B (FIG. 44B) are each characterized by the same form, which is different than the forms of either input material.

6. Hygroscopicity for Salts/Co-Crystals of Compound I

The hygroscopicity of the esylate, mesylate, HCl, and sulfate salts/co-crystals of Compound I formed via the first scale up process was analyzed. All hygroscopicity experiments covered a wide range of humidity (0 to about 90% relative humidity) and were performed at about 25° C. to assess behavior. The results are provided in subsections (a)-(d) below.

a. Compound I Esylate Form I

Compound I esylate Form I prepared from IPA in the first scale up process was assessed for hygroscopicity. The results of a GVS analysis are shown in FIG. 45 and indicate a strong influence of humidity on the sample, mainly above about 60% RH. The sample was not subject to moisture uptake in the sorption cycle between 0 and about 60% RH. The weight variation is effectively nonexistent despite the minimal weight loss observed between 0 and about 10% RH, mainly due to drying. Above about 60% RH, the sudden increase in weight (e.g., about a 35% weight change) demonstrates the marked influence of water into the sample. This trend is reversed in the desorption cycle, between about 90 and about 60% RH, where the sample loses all the water and returns to the same value measured in the sorption cycle at about 60% RH. While a large water uptake was noted, deliquescence did not result, indicating a high hydration level and surface moisture uptake. If dried to about 10% RH, the sample loses about 4.6% of mass relative to the input weight. These results indicate that the sample (Compound I esylate Form I) is hydrated.

FIG. 46A and FIG. 46B show the X-ray powder diffractograms for Compound I esylate Form I sample post and pre GVS analysis, respectively. Exposure to humidity has a strong impact on the crystalline form of the sample. Post GVS analysis, the sample shows loss of crystallinity, and the disappearance of some peaks in the X-ray powder diffractogram (FIG. 46A). Such results illustrate the structural change due to the drying effect (potentially due to the water loss) and changes that may have occurred as a result of the reversible water uptake between about 60 and about 90% RH.

b. Compound I Mesylate Form II

Compound I mesylate Form II prepared from water in the first scale up process was assessed for hygroscopicity. The results of a GVS analysis are shown in FIG. 47 and indicate the relative influence of humidity on the sample. In particular, as the relative humidity increases, the weight uptake varies accordingly. The total weight uptake from the starting point does not exceed about 1.4%. The desorption indicates that only a total of about 2% mass is lost. If this sample was fully hydrated (a mono-hydrate), the total weight loss upon drying should equate to about 3.2%.

FIG. 48A and FIG. 48B show the X-ray powder diffractograms for the Compound I mesylate Form II sample pre and post GVS analysis, respectively. Exposure to humidity does not result in a form change for this sample.

c. Compound I HCl Form I

Compound I HCl Form I prepared from water in the first scale up process was assessed for hygroscopicity. The results of a GVS analysis are shown in FIG. 49 and indicate the relative influence of humidity on the sample. In particular, the weight of the sample does not vary significantly up to about 70% RH, after which a total weight uptake of about 5.9% is observed. The desorption cycle for the sample indicates that the weight thereof reverts, at about 50% RH, to its same weight value as at the beginning of GVS analysis. Additionally, about 0.5% of mass is lost when the sample is kept under about 100% dry atmosphere.

FIG. 50A and FIG. 50B show the X-ray powder diffractograms for the Compound I HCl Form I sample post and pre GVS analysis, respectively. Exposure to humidity does not result in a form change for this sample.

d. Compound I Sulfate Form II

The form of Compound I sulfate prepared from water in the first scale up process (i.e., a form substantially similar to Form II) was assessed for hygroscopicity. The results of a GVS analysis are shown in FIG. 51 and indicate the relative influence of humidity on the sample. The GVS isotherm indicates a gradual weight gain of about 4.2% up to about 80% RH before a steep increase in weight when exposed to about 90% RH. This weight gain is lost in the same fashion in the desorption isotherm. The total weight loss when dried to 0% RH is about 5.9%.

FIG. 52A and FIG. 51B show the X-ray powder diffractograms for the crystalline Compound I sulfate sample post and pre GVS analysis, respectively. Exposure to humidity slightly increased the crystallinity of the sample without affecting the peak distribution.

7. Slurry Formation for Salts/Co-Crystals of Compound I

A series of slurry maturations in various solvents was performed to further analyze the form reproducibility/stability of the esylate, mesylate, HCl, and sulfate salts/co-crystals of Compound I. The solvents chosen were acetonitrile, EtOAc, ethanol, and IPA. The input materials were the salts/co-crystals of Compound I formed via the second scale up process. About 20 mg of each sample was charged to reflux tubes and heated with temperature cycling between about 25 and about 50° C. for about 4 days. The resulting materials were isolated by filtration and dried in vacuo at about 40° C. The results of the slurry maturations for the resulting HCl and mesylate salts/co-crystals are presented in subsections (a)-(d) below. The data for the resulting esylate and sulfate salts/co-crystals of Compound have been omitted due to notable form variation.

a. Compound I HCl Form I

The starting material used in these slurry maturations was Compound I HCl (mono-HCl) Form I prepared from about 2 equivalents of aqueous HCl and ethanol during the second scale up process. FIG. 53A shows the X-ray powder diffractograms for the Compound I HCl Form I starting material, and FIG. 53B, FIG. 53C, FIG. 53D, and FIG. 53E show the X-ray powder diffractograms for the crystalline materials isolated from the slurries comprising acetonitrile (53B), EtOAc (53C), ethanol (53D), and IPA (53E). As evident from FIG. 53A, FIG. 53B, FIG. 53C, FIG. 53D, and FIG. 53E, Compound I HCl Form I does not experience any form change upon slurrying, and experienced a minor improvement in crystallinity in all cases except EtOAc.

b. Compound I HCl Form II

The starting material used in these slurry maturations was Compound I HCl (mono-HCl) Form II prepared from about 1 equivalent of dry HCl and acetonitrile during the second scale up process. FIG. 54A shows the X-ray powder diffractograms for the Compound I HCl Form II starting material, and FIG. 54B, FIG. 54C, FIG. 54D, and FIG. 54E show the X-ray powder diffractograms for the crystalline materials isolated from the slurries comprising acetonitrile (MB), EtOAc (MC), ethanol (MD), and IPA (ME). The XRPD profiles for these materials are markedly different. Samples isolated from acetonitrile and EtOAc show a material comprised of a mixture of Compound I Form I, Compound I Form II, and possibly other forms. The sample isolated from IMA shows conversion to Compound I Form I. The sample isolated from IPA also shows conversion to Compound I Form I, yet retains some mixed features.

c. Compound I Mesylate Material A

The starting material used in these slurry maturations was Compound I mesylate (mono-mesylate) Material A prepared from ethanol during the second scale up process. FIG. 55A shows the X-ray powder diffractograms for the Compound I mesylate Material A starting material, and FIG. 55B, FIG. 55C, FIG. 55D, and FIG. 55E show the X-ray powder diffractograms for the crystalline materials isolated from the slurries comprising acetonitrile (55B), EtOAc (55C), ethanol (55D), and IPA (55E). Samples isolated from each of the solvents, while different from the input material, are nearly identical to one another in terms of their crystalline structure, which results from a mixture of forms.

d. Compound I Mesylate Form III

The starting material used in these slurry maturations was Compound I mesylate (mono-mesylate) Form III prepared from EtOAc during the second scale up process. FIG. 56A shows the X-ray powder diffractograms for the Compound I mesylate Form III starting material, and FIG. 56B, FIG. 56C, FIG. 56D, and FIG. 56E show the X-ray powder diffractograms for the crystalline materials isolated from the slurries comprising acetonitrile (56B), EtOAc (56C), ethanol (56D), and IPA (56E). Each sample isolated post slurry shows a complicated pattern likely indicative of a mixture of forms comprising Compound I mesylate Form III and other forms.

8. Polymorph Screen for the Mono-HCl Salt/Co-Crystal of Compound I

About 7 mL of 0.5M DMSO solution of Compound I free base was added slowly to about 40 mL of stirred hot ethanol (about 70° C.). About 10.5 mL of 1M aq HCl was added slowly to the stirring solution at the same temperature (about 70° C.). The solution was left to cool overnight to room temperature. The material was filtered and dried in an oven for about 72 hours.

For the polymorph screening, about 20 mg of the resulting mono-HCl salt/co-crystal of Compound I and about 1 mL of a selected solvent was added to a tube and heated to about 50° C. for about three hours to improve dissolution. Samples were filtered hot through PTFE fits to avoid crash precipitation and remove any seed. Solvents of very high boiling point that would not evaporate were placed in a genevac to speed evaporation and allow materials to crash out. XRPD was the primary tool of analysis, followed by DSC/TGA if a new form was revealed. The diffractograms used for comparisons were those of Compound I mono-HCl Form I and Compound I bis-HCl Form I. The results are presented in Table 7 below.

TABLE 7 Summary of Results for the Mono-HCl Salt/Co-Crystal Polymorph Study Solvent XRPD Tetralin Gum NMP Gum Ethylene glycol Poor diffraction DMSO Compound I di-HCl Form I Anisole Compound I mono-HCl Form I DMF Compound I di-HCl Form I Cumene Compound I mono-HCl Form I 3-Me-1-BuOH Compound I mono-HCl Form I n-BuOAc Compound I mono-HCl Form I Toluene Compound I mono-HCl Form I Dioxane Compound I mono-HCl Form I Water Compound I mono-HCl Form I Heptane Compound I mono-HCl Form I n-PrOH Compound I mono-HCl Form I IPA Compound I mono-HCl Form I CH₃CN Compound I mono-HCl Form I MEK Compound I mono-HCl Form I EtOH Compound I mono-HCl Form I EtOAc Compound I mono-HCl Form I THF Poorly diffracting MeOH Compound I mono-HCl Form I Acetone Compound I mono-HCl Form I TBME Compound I mono-HCl Form I DCM Compound I mono-HCl Form I

As consistently found by the various studies discussed in the Examples, Compound I mono-HCl Form I exhibits superior thermodynamically stability relative to the other salts/co-crystals of Compound I described herein.

9. Compound I HCl Amorphous

Compound I HCl amorphous was obtained via lyophilization of a THF/water solution comprising Compound I HCl Form I over about 4-5 days at high vacuum. The material was then subject to slurry maturations in 12 solvents, using heat/cool cycles between room temperature and about 45° C. (for about 4 days). The resulting solids were filtered and dried in vacuo at about 40° C. overnight prior to analysis by XRPD. FIG. 57A, FIG. 57B, FIG. 57C, FIG. 57D, FIG. 57E, FIG. 57F, and FIG. 57G show the X-ray powder diffractograms of the Compound I HCl amorphous starting material (57A), and the resulting Compound I HCl amorphous samples formed from slurries with cumene (57B), n-BuOAc (57C), dioxane (57D), water (57E), IPA (57F), and acetonitrile (57G). Similarly, FIG. 58A, FIG. 58B, FIG. 58C, FIG. 58D, FIG. 58E, and FIG. 58F show the X-ray powder diffractograms of the Compound I HCl amorphous starting material (58A), and the resulting Compound I HCl amorphous samples formed from slurries with MEK (58B), EtOH (58C), EtOAc (58D), TBME (58E), and DCM (58F). As evident in the diffractograms, Compound I HCl amorphous comprises an amount of Compound I HCl Form I.

FIG. 59 shows a GVS isotherm for Compound I HCl amorphous. As shown in the GVS isotherm, a large increase in mass above about 40% RH, most markedly above about 80% RH, is observed, which can be removed by exposure to drying.

A study of moisture uptake for Compound I HCl amorphous was also performed and demonstrated a gradual increase in crystallinity was observed simply by exposure to ambient conditions.

10. Compound I HCl Form I

As indicated in Table 4, Compound I HCl Form I is obtained from combining Compound I Form I and about 1 equivalent of hydrochloric acid in various solvents including DMF, 3-Me-1-BuOH, n-BuOAc, toluene, water, IPA, MEK, EtOH, DMSO or THF. Processes utilizing about 2, about 3, or about 4 equivalents of hydrochloric acid were also found to yield Compound I HCl Form I.

Compound I HCl Form I is crystalline as determined via XRPD analysis (FIG. 3). Compound I HCl Form I can be characterized by an X-ray powder diffractogram comprising the following peaks: 8.7, 15.9, and 20.0° 2θ±0.2° 2θ.

Single crystal analysis of Compound I HCl Form I yields the following unit cell dimensions:

-   -   Crystal System: Triclinic     -   Space Group: P-1     -   Unit cell dimensions: a=5.2441(3) Å, α=89.428(6°)         -   b=11.3283(9) Å, β=85.493(5°)         -   c=20.1798(13) Å, γ=84.008(6)°

Compound I HCl Form I can be characterized by a differential scanning calorimetry (DSC) curve comprising an endotherm with onset at about 288° C. and a peak maximum at about 293° C. (FIG. 36).

Compound I HCl Form I is characterized by a thermogravimetric analysis (TGA) thermogram showing a weight loss of about 3.5% below about 100° C., and a weight loss of about 4.5% at about 270° C. (FIG. 36).

Compound I HCl Form I is characterized by dynamic vapor sorption (DVS) analysis showing minimal moisture uptake with no hysteresis between about 40% and about 90% RH. While the DVS analysis additionally shows a weight of up to about 3.5% below about 10% RH, complete moisture re-uptake is observed about 20% RH. Accordingly, de-hydration and re-hydration of Compound I HCl Form I was found to be reversible and does not disturb the crystalline structure thereof. An exemplary DVS curve of Compound I HCl Form I is provided in FIG. 60. In view of the DVS analysis, compound I HCl Form I may be characterized as a monohydrate.

Compound I HCl Form I exhibits solubility in a variety of solvents and solvent systems. A summary of the approximate kinetic solubility of Compound I HCl Form I in organic solvents, simulated biological fluids, and common pharmaceutical co-solvents is provided in Tables 8-10, respectively.

A thermodynamic pH-solubility profile of Compound I HCl Form I in various buffer or non-buffer solutions is further provided in FIG. 61. FIG. 61 additionally includes the thermodynamic pH-solubility profile of Compound I free base. It is of note that no data is shown in the profile of Compound I free base below a pH of about 2.0, as Compound I free base converted to Compound I HCl Form I below a pH of about 2.0. Similarly, no data is shown in the profile of Compound I HCl Form I above a pH of about 3.0, as Compound I HCl Form I converted to Compound I free base above a pH of about 3.0. The thermodynamic solubility of the Compound I free base and Compound I HCl Form I systems was determined after 7 days of shaking the respective system at about 37° C. water bath.

Compound I HCl Form I additionally exhibits desirable stability. For instance, Compound I HCl Form I in powder form did not exhibit any form change after about 6 months at about 40° C./75% RH under open dish conditions as determined by XRPD, TGA and DSC.

The stability of Compound I HCl Form I in buffer solutions over a pH range of about 1.2 to about 10.0 was also evaluated. These solutions were stored at about 60° C., and assayed for pH and % remaining at 2 days. Data indicated that Compound I HCl Form I was most stable at a pH of about 4.5 (FIG. 62).

Compound I HCl Form I also exhibited polymorphic stability at elevated temperatures. Dry-heating Compound I HCl Form I at about 50° C. for about 72 hours did not change the crystalline form of Compound I HCl Form I as determined by XRPD, DSC and proton NMR. Heating Compound I HCl Form I up to about 120° C. inside TGA until approximately 3% weight loss showed a slight loss of crystallinity, but without a new form appearing. After re-hydrating this post-TGA material (3 days at about 60% RH), DSC showed no gross effect upon the polymorphism, but amorphous content did appear (Tg at about 250° C.).

11. Salt Screening

Additional salt screening for solid forms was conducted by combining Compound I with various acids. The procedure used was as follows: About 20 mg of Compound I free base Form I was weighed into a 2-mL glass vial. A corresponding amount of acid, with the molar ratio of 1:1 acid:Compound I, was added. 0.5 mL of the corresponding solvent was added into the glass vial. The mixture was stirred at RT (25±3° C.) for 3 days. The solid was isolated via centrifugation, and the solid was dried at RT overnight. XRPD analysis was conducted on dried solids. Where provided, the molar ratio of acid: free base was determined by integration of NMR peaks. A summary of the screening experiments is presented in Table 11. Summary of characterization of the salt forms is presented in Table 12.
